Electrophile Addition vs. SN2 Reaction

Postby awolff_1D » Sat Mar 12, 2016 6:59 pm

What's the difference between an electrophile addition reaction and an SN2 reaction?

SN2 is any kind of nucleophilic substitution reaction: https://en.wikipedia.org/wiki/SN2_reaction
Electrophilic Addition is a reaction where a pi-bond (generally a double bond) attacks an electrophile: https://en.wikipedia.org/wiki/Electrophilic_addition

Another main difference between electrophilic addition and the bimolecular nucleophilic substitution reaction is that they have two steps and one step, respectively. The electrophilic addition reaction has two steps meaning two transition states, while the bimolecular nucleophilic substitution reaction has only one transition state. With this, there is two different activation energies to consider with the two transition states for SN1 and there is only one activation energy to consider with the one transition state in SN2.



Here is an picture representing the different energy diagrams for the two types of reactions:
